Document Summary
Force maximum potential difference a battery or power source can give a circuit lemf or e) circuit. Diagrams symbols use logical picture to portray what of a circuit is connected to what battery. Sum of all potential differences around a loop i closed path is zero. Dv - te e current moves from positive to. R negative , moves but potential difference from negative to positive. Problem current remains the same me . gg#. u. ge:oeap::s. u:siti:nisaen:nhea : battery creates. Dv which potential do work energy for the supplies to lightbulb. Ie because electric force does work on charges. I ( ret r2 ) t r2 t: can add up all resistors change its value and make a simpler diagram. Ammeter measures current when placed in the circuit in series resistance of ammeter is negligible. Ff- short to circuit ideal battery snorting it with an ideal wine will cause.
